RESUMO
BACKGROUND AND OBJECTIVE: One-stop clinics have emerged as a tool to optimize the therapeutic management of cancer patients. The main purpose of this study was to assess the role of the one-stop hematuria clinic (OSHC), as compared to a conventional clinic (CC), on the overall and disease-free survival of patients with bladder cancer. METHODS: A five-year follow-up retrospective and single-center study was conducted in patients with primary bladder tumor diagnosed between 2006 and 2015. The primary outcomes were five-year overall survival and one-year relapse rate. RESULTS: A total of 394 patients (160 in OSHC and 234 in CC) were included. No differences were observed in terms of age, sex, smoking habit or risk group between the OSHC and CC groups. The average times from first symptom to diagnosis (24.9 ± 29.1 vs. 100.7 ± 93.6 days) and from first symptom to treatment (70.2 ± 34.0 vs. 155.0 ± 102.9 days) were significantly lower in the OSHC group than in the CC group (p < 0.001 each). There was no significant difference in the five-year survival rate between OSHC and CC (103/160 vs. 150/234, respectively; p = 0.951), although the proportion of relapses during the first year was significantly lower in the OSHC group (35/139, 25.2%) than in the CC one (74/195, 38.0%; p = 0.02). CONCLUSIONS: OSHC significantly reduced the diagnosis and treatment times. The early-relapse rate was significantly lower in the OSHC group, although the five-year survival rate was similar.

To examine the effect on functional shoulder scores of Bankart repair with arthroscopic subscapularis tendon augmentation applied to cases of anterior shoulder instability withâ <â 25% glenoid defect and ligament-labral failure. A total of 83 patients underwent Bankart repair with subscapularis tendon augmentation between 2015 and 2021. The range of movement of the patients was measured by 2 doctors using a goniometer. The Constant Murley score, American Shoulder and Elbow Surgeons score, Rowe score, and the University of California at Los Angeles scores were recorded preoperatively and postoperatively. Statistically significant increases were determined in the postoperative functional scores compared to the preoperative values as mean 41.4â ±â 2.08 unit increase in the Constant Murley score, mean 41.4â ±â 1.8 unit increase in the American Shoulder and Elbow Surgeons score, mean 13.8â ±â 1.45 unit increase in the University of California at Los Angeles and mean 49.3â ±â 7.45 unit increase in the Rowe score (Pâ =â .001; Pâ <â .01). Compared with the preoperative evaluation, there was found to be a postoperative statistically significant unit decrease of 10.2â ±â 1.47 in the external rotation measurement (Pâ =â .001; Pâ <â .01). The number of dislocations was determined to have a negative correlation with the internal rotation measurements (râ =â -0.305; Pâ =â .005; Pâ <â .01), and a weak negative statistically significant relationship with external rotation measurements (râ =â -0.329; Pâ =â .002; Pâ <â .01). Unlike other techniques, as this repair technique includes both the tendon and the capsule as a single piece, it was seen to be a sufficient and reliable technique that is easy-to apply.

Chronic subdural hematoma (cSDH) is an encapsulated collection of blood and blood degradation products between dural border cell layers, the pathophysiology of formation and expansion of which is still debatable. It is usually seen in the elderly population, and surgical evacuation is the primary mode of treatment. The main hurdle in the treatment of cSDH is postoperative recurrences and the need for repeat operations. A few authors have classified cSDH into homogenous, gradation, separated, trabecular, and laminar types based on the internal architecture of hematoma and proposed that separated, laminar, and gradation types of cSDH have a high propensity of recurrence after surgery. A similar problem was described with multi-layered or multi-membrane cSDH. Based on the most accepted theory of formation and expansion of cSDH that suggests a complex and vicious process of membrane formation, chronic inflammation, neoangiogenesis, rebleeding from fragile capillaries, and increased fibrinolysis, we propose our theory of intermembranous placement of oxidized regenerated cellulose and membrane tucking using ligature clips to prevent recurrence in multi membranous cSDH by ceasing the ongoing cascade in hematoma's internal milieu and thus preventing recurrence and reoperation in such cases. This is the first in the world literature report describing such a technique for treating multi-layered cSDH and in our series, the reoperation and postoperative recurrence rates were 0% in patients treated by the described technique.

In patients with severe acute alcohol-related hepatitis not responding to medical therapy, early liver transplantation (LT) represents the only effective therapy and, when performed within strict and well-defined protocols, it is associated with a clear survival benefit and acceptable rates of return to alcohol use after transplantation. However, there is still high variability in access to LT for patients with severe alcohol-related hepatitis, mainly due to a persistent overemphasis in the pre-LT evaluation on duration of pre-transplant abstinence and the stigma that patients with alcohol-related liver disease often experience, leading to marked inequity of access to this potentially lifesaving procedure and negative health outcomes. Therefore, there is an increasing need for prospective multicentre studies focusing on pre-transplant selection practices and on better interventions to treat alcohol use disorder after LT.

BACKGROUND: Considering that ablation of atypical AVNRT may be unsuccessful after ablation at the right posterior septum, in this study, we aimed to present an optimal method for ablation of atypical AVNRT. Also, we evaluated the efficacy of this technique for preventing recurrences. METHODS: This is a prospective, double-center study. It was conducted on 62 patients with atypical AVNRT referred for radiofrequency ablation. The patients were randomly divided into two groups before ablation: 1-Group A (n = 30): treated with conventional ablation at the anatomic area of the slow pathway; 2-Group B (n = 32): ablation was done 2 mm higher in the septum during fluoroscopy. RESULTS: The mean age of patients in groups A and B were 54 ± 11.7 and 55 ± 12.2, respectively (P = 0.43). In group A, ablation was successful in 24 (80%) patients following right-sided slow pathway ablation, and the remaining patients required further treatment with either a left-side approach (N = 4, 13.3%) or ablation of additional regions (N = 2, 6.7%). In group B, ablation was successful in all patients. After a 48-month follow-up, recurrence of symptomatic atypical AVNRT was detected in 4 (13.3%) patients of group A and none of group B patients (p < 0.001). CONCLUSION: In patients with atypical AVNRT, ablation 2 mm above the conventional area is more promising regarding success rate and recurrence of the arrhythmia.

Fecal microbiota transplantation (FMT) is highly effective in preventing recurrent Clostridioides difficile infection (rCDI). However, the mechanisms underpinning its clinical efficacy are incompletely understood. Herein, we provide an overview of rCDI pathogenesis followed by a discussion of potential mechanisms of action focusing on the current understanding of trans-kingdom microbial, metabolic, immunological, and epigenetic mechanisms. We then outline the current research gaps and offer methodological recommendations for future studies to elevate the quality of research and advance knowledge translation. By combining interventional trials with multiomics technology and host and environmental factors, analyzing longitudinally collected biospecimens will generate results that can be validated with animal and other models. Collectively, this will confirm causality and improve translation, ultimately to develop targeted therapies to replace FMT.

BACKGROUND: The death of oral keratinocytes is a crucial step in the emergence of recurrent aphthous stomatitis (RAS, also known as aphthae or aphthous ulcers). Since there are no experimental models available to research aphthous ulcers, little is understood about this process. We hypothesize that saliva can be a data bank of information that offers insights on epithelial damage. METHODS: In this case-crossover study, we assessed the salivary proteome of patients with RAS (n = 36) in the presence and absence of ulcers using discovery proteomics and bioinformatics. Additionally, we contrasted these patterns with those of healthy individuals (n = 31) who had no prior aphthous ulceration. RESULTS: Salivary proteome showed that during the ulcerative phase, controlled cell death was downregulated. Due to its ability to distinguish between individuals with and without ulcers, the ATF6B protein raises the possibility that endoplasmic reticulum (ER) stress is responsible for the damage that leads to the death of oral keratinocytes. The high abundance of TRAP1 and ERN1 matches with this biological discovery. The type of death is immunogenic, according to the functional data found in a cell death database. CONCLUSION: We identified a cellular process that can lead to the death of oral keratinocytes in the etiopathogenesis process of RAS. Future studies should be conducted to identify what is responsible for the increase in ER stress signaling that would lead to an anti-cell death response.

Chimeric antigen receptor (CAR) T-cells are an emerging therapy for the treatment of relapsed/refractory B-cell malignancies. While CD19 CAR-T cells have been FDA-approved, CAR T-cells targeting CD22, as well as dual-targeting CD19/CD22 CAR T-cells, are currently being evaluated in clinical trials. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of CD22-targeting CAR T-cell therapies. We searched MEDLINE, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials from inception to March 3rd 2022 for full-length articles and conference abstracts of clinical trials employing CD22-targeting CAR T-cells in acute lymphocytic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). The primary outcome was best complete response (bCR). A DerSimonian and Laird random-effects model with arcsine transformation was used to pool outcome proportions. From 1068 references screened, 100 were included, representing 30 early phase studies with 637 patients, investigating CD22 or CD19/CD22 CAR T-cells. CD22 CAR T-cells had a bCR of 68% [95% CI, 53-81%] in ALL (n= 116), and 64% [95% CI, 46-81%] in NHL (n= 28) with 74% and 96% of patients having received anti-CD19 CAR T-cells previously in ALL and NHL studies respectively. CD19/CD22 CAR T-cells had a bCR rate of 90% [95% CI, 84-95%] in ALL (n= 297) and 47% [95% CI, 34-61%] in NHL (n= 137). The estimated incidence of total and severe (grade ≥3) CRS were 87% [95% CI, 80-92%] and 6% [95% CI, 3-9%] respectively. ICANS and severe ICANS had an estimated incidence of 16% [95% CI, 9-25%] and 3% [95% CI, 1-5%] respectively. Early phase trials of CD22 and CD19/CD22 CAR T-cells show high remission rates in ALL and NHL. Severe CRS or ICANS were (1)rare and dual-targeting did not increase toxicity. Variability in CAR construct, dose, and patient factors amongst studies limits comparisons, with long-term outcomes yet to be reported.

The year 2023 marks the 100th anniversary of the first successful valvotomy for mitral valve stenosis by Elliott C. Cutler in 1923. Closed-chest mitral valve commissurotomy developed further before being replaced by an open procedure after the advent of the heart-lung machine. Currently, because of the almost complete disappearance of rheumatic disease in the Western World, mitral commissurotomies are infrequently performed in those countries, although the procedure-either closed or open-is still performed in developing countries and select patients. This review retraces the 100-year journey from a historic operation to the current era-a milestone in the treatment of patients with mitral stenosis.

BACKGROUND: Despite accumulating evidence of an association between stressful life events and psychosis relapse, the extent to which this is a causal relationship remains unclear. We aimed to examine the association between exposure to, and number of, stressful life events after initial psychosis onset and psychosis relapse. METHODS: In this 2-year prospective observational study, we recruited individuals with first-episode psychosis, aged 18-65 years, who presented to psychiatric services in south London, UK. Participants were assessed via interview, with additional data obtained from electronic clinical records. Stressful life events were recorded at psychosis onset and during the 2-year follow-up using a brief questionnaire that assesses 12 major life events. Psychosis relapse was defined as inpatient admission because of symptom exacerbation within 2 years from psychosis onset. We examined the time to first psychosis relapse and the number and length of relapses using survival and binomial regression analyses. We used fixed-effects regression and cross-lagged path analysis to examine the directionality of effects and control for unmeasured confounders. FINDINGS: Between April 12, 2002, and July 26, 2013, 256 individuals with first-episode psychosis (100 [39%] female and 156 [61%] male; 16 [6%] Asian, 140 [55%] Black African or Caribbean, 86 [34%] White, and 14 [6%] mixed ethnicity) were recruited, with a mean age of onset of psychosis of 28·06 years (SD 8·03; range 17·21-56·03). 93 (36%) participants experienced at least one relapse during the 2-year follow-up. 253 individuals had all relevant data and were included in analyses. For people exposed to stressful life events after the onset of psychosis, the adjusted hazard (hazard ratio [HR] 2·60, 95% CI 1·63-4·16, p<0·0001), incidence (incidence rate ratio [IRR] 1·87, 1·24-2·80, p=0·0026), and length (IRR 2·53, 1·40-4·67, p=0·0011) of relapse were greater than for those who were unexposed. These relationships were dose dependent (HR 1·36; 1·09-1·69, p=0·0054; incidence IRR 1·26, 1·02-1·53, p=0·023; length IRR 1·52, 1·12-2·12, p=0·0028). Adjusted fixed-effects models showed a higher (odds ratio [OR] 3·82, 1·82-8·00, p=0·0004) and dose-dependent (OR 1·62, 1·18-2·21, p=0·0028) risk of relapse when stressful life events preceded relapse compared with the period when they did not. Cross-lagged path analysis confirmed an effect of stressful life events on the number of subsequent relapses (ß=0·66, p=0·0055) that was dose dependent (ß=0·29, p=0·029), but it did not show an effect of relapses on subsequent risk or number of stressful life events. INTERPRETATION: These results provide converging evidence of a causal effect of stressful life events on the risk of relapse in psychosis. They suggest that there is a need to develop interventions at the individual and health-service level that could mitigate the harmful effects of stressful life events.

Objective: To investigate the effectiveness of arthroscopic autologous iliac bone grafting with double-row elastic fixation in treatment of recurrent anterior shoulder dislocation combined with massive glenoid bone defects. Methods: Between January 2018 and December 2021, 16 male patients with recurrent anterior shoulder dislocation combined with massive glenoid bone defects were treated with arthroscopic autogenous iliac bone grafting and double-row elastic fixation. The patients were 14-29 years old at the time of the first dislocation, with an average age of 18.4 years. The causes of the first dislocation included falling injury in 5 cases and sports injury in 11 cases. The shoulders dislocated 4-15 times, with an average of 8.3 times. The patients were 17-37 years old at the time of admission, with an average age of 25.1 years. There were 5 left shoulders and 11 right shoulders. The preoperative instability severity index (ISIS) score of the shoulder joint was 5.8±2.1, and the Beighton score was 4.3±2.6. The University of California Los Angeles (UCLA) score, Constant score, American Shoulder and Elbow Surgeons (ASES) score, and Rowe score were used to evaluate shoulder function, and the degree of the glenoid bone defect repair was observed based on CT after operation. Results: All incisions healed by first intention, and no complication such as incision infection or neurovascular injury occurred. The patients were followed up 12 months. At 12 months after operation, UCLA score, Constant score, ASES score, and Rowe score all significantly improved when compared with the scores before operation ( P<0.05). CT imaging showed the degree of glenoid bone defect was significantly smaller at immediate, 6 and 12 months after operation when compared with that before operation ( P<0.05), and the bone blocks healed with the scapula, and bone fusion had occurred at 12 months. Conclusion: Arthroscopic autologous iliac bone grafting with double-row elastic fixation is a safe treatment for recurrent anterior shoulder dislocation combined with massive glenoid bone defects, with good short-term effectiveness.

BACKGROUND: In Lung adenocarcinoma (LUAD), targeted therapies and immunotherapies have moved from metastatic to early stage and stratification of the relapse risk becomes mandatory. Here we identified a miR-200 based RNA signature that delineates Epithelial-to-mesenchymal transition (EMT) heterogeneity and predicts survival beyond current classification systems. METHODS: A miR-200 signature was identified using RNA sequencing. We scored the miR-200 signature by WISP (Weighted In Silico Pathology), used GSEA to identify pathway enrichments and MCP-counter to characterize immune cell infiltrates. We evaluate the clinical value of this signature in our series of LUAD and using TCGA and 7 published datasets. RESULTS: We identified 3 clusters based on supervised classification: I is miR-200-sign-down and enriched in TP53 mutations IIA and IIB are miR-200-sign-up: IIA is enriched in EGFR (p < 0.001), IIB is enriched in KRAS mutation (p < 0.001). WISP stratified patients into miR-200-sign-down (n = 65) and miR-200-sign-up (n = 42). Several biological processes were enriched in MiR-200-sign-down tumors, focal adhesion, actin cytoskeleton, cytokine/receptor interaction, TP53 signaling and cell cycle pathways. Fibroblast, immune cell infiltration and PDL1 expression were also significantly higher suggesting immune exhaustion. This signature stratified patients into high-vs low-risk groups, miR-200-sign-up had higher DFS, median not reached at 60 vs 41 months and within subpopulations with stage I, IA, IB, or II. Results were validated on TCGA data on 7 public datasets. CONCLUSION: This EMT and miR-200-related prognostic signature refines prognosis evaluation independently of tumor stage and paves the way towards assessing the predictive value of this LUAD clustering to optimize perioperative treatment.

Objective: To explore the effectiveness and advantages of using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair compared with traditional arthroscopic suture shuttle. Methods: The clinical data of 41 patients with Bankart lesion, who met the selection criteria and were admitted between August 2019 and October 2021, was retrospectively analyzed. Under arthroscopy, the inferior capsulolabral complex was stitched with Fastpass Scorpion suture passer in 27 patients (FS group) and with arthroscopic suture shuttle in 14 patients (ASS group). There was no significant difference between the two groups ( P>0.05) in gender, age, injured side, frequency of shoulder dislocation, time from first dislocation to operation, and preoperative Rowe score of shoulder. Taking successful suture and pull-tightening as the criteria for completion of repair, the number of patients that were repaired at 5â¶00 to 6â¶00 (<6:00) and 6â¶00 to 7â¶00 positions of the glenoid in the two groups was compared. The operation time, and the difference of Rowe shoulder score betwee pre- and post-operation, the occurrence of shoulder joint dislocation, the results of apprehension test, and the constituent ratio of recovery to the pre-injury movement level between the two groups at 1 year after operation. Results: Both groups completed the repair at 5â¶00 to 6â¶00 (<6â¶00), and the constituent ratio of patients completed at 6â¶00 to 7â¶00 was significantly greater in the FS group than in the ASS group ( P<0.05). The operation time was significantly shorter in the FS group than in the ASS group ( P<0.05). All incisions in the two groups healed by first intention. All patients were followed up 12-36 months (mean, 19.1 months). No anchor displacement or neurovascular injury occurred during follow-up. Rowe score of shoulder in the two groups significantly improved at 1 year after operation than preoperative scores ( P<0.05), and there was no significant difference in the difference of Rowe shoulder score between pre- and post-operation between the two groups ( P>0.05). At 1 year after operation, no re-dislocation occurred, and there was no significant difference in the apprehension test and the constituent ratio of recovery to the pre-injury movement level between the two groups ( P>0.05). Conclusion: Compared with the arthroscopic suture shuttle, using Fastpass Scorpion suture passer to stitch the inferior capsulolabral complex in arthroscopic Bankart repair is more convenient, saves operation time, and has good effectiveness.

The shoulder joint is the most prone to dislocation in the whole body, and more than 95% of them are anterior dislocation. Improper treatment after the initial dislocation is easy to lead to recurrent anterior dislocation or anterior shoulder instability, and the outcomes following conservative treatment is poor. Anterior shoulder instability can damage the soft tissue structure and bone structure that maintain the stability of shoulder joint, among which bone structure is the most important factor affecting the stability of shoulder joint. Diagnosis should be combined with medical history, physical examination, and auxiliary examination. Currently, three-dimensional CT is the most commonly used auxiliary examination means. However, various bone defect measurement and preoperative evaluation methods based on three-dimensional CT and the glenoid track theory have their own advantages and disadvantages, and there is still a lack of gold standard. Currently, the mainstream treatment methods mainly include Bankart procedure, coracoid process transposition, glenoid reconstruction with free bone graft, Bankart combined with Remplissage procedure, and subscapular tendon binding tamponade, etc. Each of these procedures has its own advantages and disadvantages. For the diagnosis and treatment of anterior shoulder instability, there are still too many unknown, further research and exploration need to be studied.

Objective: To investigate the mid-term effectiveness of arthroscopic Bankart repair for recurrent anterior shoulder dislocation. Methods: The clinical data of 107 patients with recurrent anterior shoulder dislocation who met the inclusion criteria between January 2017 and June 2021 was retrospectively analyzed, and all patients underwent arthroscopic Bankart repair. There were 88 males and 19 females. The age of the primary dislocation ranged from 13 to 48 years (mean, 23.3 years). The number of preoperative dislocations was 2-160 times (median, 7 times). The duration of preoperative instability was 0.2-240.0 months (median, 36.0 months). The mean age at operation was 28.2 years (range, 16-61 years). There were 43 cases of left shoulder and 64 cases of right shoulder. The proportion of glenoid defects in 63 patients was 1.7%-16.1% (mean, 8.1%). MRI showed that none of the patients had rotator cuff tears or shoulder stiffness. The CT three-dimensional reconstruction was performed at 1 day after operation to evaluate the distribution of implanted anchors and the occurrence of glenoid split fracture and whether there were nails pullout at the implant site. The postoperative complications were observed, and the pain and function of the shoulder were evaluated by visual analogue scale (VAS) score, Rowe score, Constant-Murley score, and American Shoulder and Elbow Surgeons (ASES) score. The recurrence of instability, the results of apprehension test, the number of patients who returned to preoperative sports level, and the satisfaction rate of patients were recorded. Results: All patients were successfully operated and were followed up 20-73 months (mean, 41.5 months). All incisions healed by first intention. The CT three-dimensional reconstruction at 1 day after operation showed that the anchors were located at the 2 : 00-5 : 30 positions of the glenoid, and there was no glenoid split fracture or nails pullout at the implant site. At last follow-up, VAS score was significantly lower than that before operation, and Rowe score, Constant-Murley score, and ASES score were significantly higher than those before operation ( P<0.05). Seven patients (6.5%) had recurrence of anterior shoulder dislocation at 23-55 months (mean, 39.9 months) after operation, including 6 cases of dislocation and 1 case of subluxation. At last follow-up, 51 patients (47.7%) returned to preoperative sports level, and 11 patients (10.3%) had a positive apprehension test. The patients' satisfaction rate was 90.7% (97/107). Among the 10 patients who were not satisfied with the surgical effectiveness, 7 patients had postoperative recurrence of instability, and 3 patients felt that they did not return to preoperative sports level. Conclusion: Arthroscopic Bankart repair has good mid-term effectiveness in patients with recurrent anterior shoulder dislocations, minimal or no glenohumeral bone defects and low sports need.

Objective: To review the research progress of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation, and provide a guide for further research on bone graft resorption. Methods: The relevant literature in recent years was extensively reviewed. The pathogenesis, classification, risk factors, clinical function impact, and management of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation were summarized. Results: Bone graft resorption is the common complication after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation. Stress shielding and poor blood supply may contribute to the occurrence of bone graft resorption. The absence of significant preoperative glenoid bone loss, open procedure, earlier graft healing may to be the risk factors for bone graft resorption. Various assessment methods and classification systems are used to evaluate the region and severity of bone graft resorption. Partial resorption may be considered as a natural glenoid remodeling process after the surgery, but severe and complete resorption is proved to be one of the reasons for failed procedures and there is no effective measure to prevent it, except for accepting revision surgery. Conclusion: The pathogenesis, risk factors, clinical function impact of bone graft resorption after Latarjet procedure for the treatment of recurrent anterior shoulder dislocation has not been fully elucidated and there is a lack of effective management strategies, so further clinical and basic researches are needed.

ABSTRACT: Myelodysplastic syndromes (MDSs) are characterized by a clonal proliferation of hematopoietic stem cells with potential life-threatening cytopenia(s) and transformation to acute myeloid leukemia. Individualized risk stratification is evolving with new molecular models, such as the Molecular International Prognostic Scoring System, for better estimation of leukemic transformation and overall survival. The only potential cure for MDSs is allogeneic transplant, although it is underutilized in MDSs because of advanced patient age and multiple comorbidities. Optimization of transplant relies on improved identification of high-risk patients pretransplant, using targeted therapies leading to deeper molecular response, developing lower toxicity conditioning regimens, engineering better molecular tools for early detection and relapse monitoring, and adding maintenance treatment strategies for high-risk patients posttransplant. This review provides an overview of transplant in MDSs with updates, future directions, and role for novel therapies.

OBJECTIVE: Subdural drainage reduces recurrence after evacuation of chronic subdural hematoma (CSDH). In the present study, the authors investigated the dynamics of drain production and potentially contributing factors for recurrence. METHOD: Patients treated with a single burr hole evacuation of CSDH between April 2019 and July 2020 were included. Patients were also participants in a randomized controlled trial. All patients included, had a passive subdural drain for exactly 24 hours. Drain production, Glasgow Coma Scale score, and degree of mobilization was recorded every hour for 24 hours. A CSDH successfully drained for 24 hours is referred to as a "case". Patients were followed for 90 days. Primary outcome was symptomatic recurrent CSDH requiring surgery. RESULTS: A total of 118 cases from 99 patients were included in the study. Of the 118 cases, 34 (29%) had spontaneous drain cessation within the first 0-8 hours after surgery (Group A), 32 (27%) within 9-16 hours (Group B), and 52 (44%) within 17-24 hours (Group C). Hours of production (P < 0.000) and total drain volume (P = 0.001) were significantly different between groups. The recurrence rate was 26.5% in group A, 15.6% in group B, and 9.6% in group C (P = 0.037). Multivariable logistic regression analysis show that cases in group C (OR: 0.13, P = 0.005) are significantly less likely to recur compared to group A. Only in 8 of the 118 cases (6.8%), the drain started draining again after an interval of three consecutive hours. CONCLUSIONS: Early spontaneous cessation of subdural drain production seems to be associated with increased risk of recurrent hematoma. Patients with early cessation of drainage did not benefit from further drain time. Observations of the present study indicate personalized drainage discontinuation strategy as a potentially alternative to a specific discontinuation time for all CSDH patients.

BACKGROUND: Current studies indicate that fluorine-18-fluorodeoxyglucose positron emission tomography/ computed tomography ([18F]FDG PET/CT) is the most accurate imaging modality for the detection of relapsed locally advanced non-small cell lung cancer (NSCLC) after curatively intended chemoradiotherapy. To this day, there is no objective and reproducible definition for the diagnosis of disease recurrence in PET/CT, the reading of which is relevantly influenced by post radiation inflammatory processes. The aim of this study was to evaluate and compare visual and threshold-based semi-automated evaluation criteria for the assessment of suspected tumor recurrence in a well-defined study population investigated during the randomized clinical PET-Plan trial. METHODS: This retrospective analysis comprises 114 PET/CT data sets of 82 patients from the PET-Plan multi-center study cohort who underwent [18F]FDG PET/CT imaging at different timepoints for relapse, as suspected by CT. Scans were first analyzed visually by four blinded readers using a binary scoring system for each possible localization and the associated reader certainty of the evaluation. Visual evaluations were conducted repeatedly without and with additional knowledge of the initial staging PET and radiotherapy delineation volumes. In a second step, uptake was measured quantitatively using maximum standardized uptake value (SUVmax), peak standardized uptake value corrected for lean body mass (SULpeak), and a liver threshold-based quantitative assessment model. Resulting sensitivity and specificity for relapse detection were compared to the findings in the visual assessment. The gold standard of recurrence was independently defined by prospective study routine including external reviewers using CT, PET, biopsies and clinical course of the disease. RESULTS: Overall interobserver agreement (IOA) of the visual assessment was moderate with a high difference between secure (ĸ = 0.66) and insecure (ĸ = 0.24) evaluations. Additional knowledge of the initial staging PET and radiotherapy delineation volumes improved the sensitivity (0.85 vs 0.92) but did not show significant impact on the specificity (0.86 vs 0.89). PET parameters SUVmax and SULpeak showed lower accuracy compared to the visual assessment, whereas threshold-based reading showed similar sensitivity (0.86) and higher specificity (0.97). CONCLUSION: Visual assessment especially if associated with high reader certainty shows very high interobserver agreement and high accuracy that can be further increased by baseline PET/CT information. The implementation of a patient individual liver threshold value definition, similar to the threshold definition in PERCIST, offers a more standardized method matching the accuracy of experienced readers albeit not providing further improvement of accuracy.

PURPOSE: To analyze epidemiology, clinical features, and surgical outcomes of type III acute acquired concomitant esotropia (Bielschowsky esotropia (BE)). METHODS: The medical charts of patients diagnosed with acquired concomitant esotropia between 2013 and 2021 were reviewed. Assessed data were age, gender, age at diplopia onset, age at the diagnosis, refraction, visual acuity, neuroimaging, diplopia onset, angle of deviation, stereopsis, surgical procedure, amount of surgery, and relapse of diplopia after surgery. Moreover, we investigated the correlation between the use of electronic devices and the onset of diplopia. RESULTS: One hundred seventeen patients (mean age 35.07 ± 15.81 years) were included in the study. The mean delay to the diagnosis was 3.29 ± 3.62 years. Myopia range was 0 to 17 diopters spherical equivalent. 66,3% spent more than 4 hours a day using laptops, tablets, or smartphones at the onset of diplopia, and 90,6% presented a subacute onset. None showed neurologic signs or symptoms. Patients who underwent surgery were ninety-three, with a rate of surgical success of 93.6%, and a relapse rate of 17.2%. A negative correlation resulted between pre-operative deviation and age at diagnosis (ρ = -0.261; p<0.05), whereas factors associated with surgical failure were older age at diplopia onset (p = 0.042) and longer delay between onset and diagnosis (p = 0.002). CONCLUSION: We registered an outstanding increase in prevalence of BE, which could be related to the exponential increase in the use of electronic devices for professional, educational, and recreational purposes. A prompt diagnosis and an augmented dose of surgery allows good motor and sensory results.
